I never understood why anyone would want to film/picture other customers. I am appalled when i see some youtube bloggers blatantly showing crew/pax. When I travel, one of the reasons for choosing F is to stay away from people and commotion so i can focus on what i need, and having someone like this on my flight i might even consider asking to offboard myself as it's just disruptive to the point of being impossible to work or rest.
